Yes, it really can be that simple. In fact, if you want to use the defaults
for all the options, you can even write the above as:

var config = cg.parser(<filename>);

The data returned from the parsers "getall" method is a standard
JavaScript Object masquerading as a hash. You can reference items in
that Object as you would items in any other JavaScript object.

For more information about available options and the format of the file
itself, please see the documentation of Perl's Config::General and its
two sub-modules, Config::General::Extended and Config::General::Interpolated.

I have done a lot of work to make as many features of the Perl module
available to users of this NodeJS module. Two features that are missing are
the ability to 'tie' to a backing-store (Config::General's '-Tie' parameter)
and the functional interface. The "AUTOLOAD methods" feature of
Config::General is emulated, to a degree, via the use of ES6 (Harmony)
Proxies. To use that feature, you must start your process with either the
'--harmony-proxies' or '--harmony' flag.

Please leave information about any missing features or founds bugs on the
bug-tracker provided by Github for the project.
